cb2 2012-09-09, single SD card version
power supply is a 3 A @5 V brick
microsoft mouse and kb on usb, typical monitor on hdmi
take sandisk ultra 16GB class10
card tests ok with h2testw
tried fedora 22, dd .img to /dev/sdb, disconnect-reconnect sd card, mount sdb3, dd appropriate uboot,
start cb2, system boots, lots of errors.
reaches right before presenting login, stops there.
blew compressed air into sd slot.
tried different sd card (kingston 8GB class4)
dd cb2 vanilla xenial armbian server .img to sandisk sdcard
cb2 insists on booting from nand, trying to mount /dev/mmcblk0p1 says no valid partition whatsoever
tried bs=1M, bs=10M.
tried different sdcard.
tried dd under windows 10 on desktop
tried dd under lubuntu on laptop
the linaro installation existing in nand boots fine. has about a page worth of errors in dmesg, but it boots, X and all.
second card tests ok with h2testw
wrote a script to check reading and writing to sd card, on the cb2, with dd and sha1, sha256 and md5
card works ok
not sure what else to try
does this work for you guys? I mean, you guys developing armbian, have you successfully booted this image on a cb2? Can you give it a try?
